Hi, My project is looking for a method of controlling voltage linearly from 0 to75(up to 100V), This is for controlling the piezo accurator. I am really new to Arduino, can anyone help show me any similar method or project so I can start with>> Thank you very much for your help my friends,

Which frequency, which actuator?

[image] zhrhxx: controlling the piezo accurator. I am really new to Arduino Something to do with refrigeration? Can you help us, we are really new to refrigeration. You could say we are "starting from cold".

Linearly is going to be difficult and likely beyond your ability. Simply building a voltage generator that can be controlled from arduino is a lot easier. Google Cockcroft-Walton multiplier. It's not hard to build one. An arduino and a handful of diodes and capacitors is really all you need.

Hi, @zhrhxx
Welcome to the forum.

Please read the post at the start of any forum , entitled "How to use this Forum".

When you say "piezo accurator" do you mean "piezo actuator"?

Can you please post a link to specs/data of the device?

Thanks.. Tom...
